Hi All-
I’m a new gatling(v2.3.1) user who is trying to use gatling to test a spring webflux application.
I’m getting the following error, and I believe it’s because async-http-client version 2.0.39 has it’s own set of netty classes.
I’m using the com.github.lkishalmi.gatling gradle plugin(v0.7.1). Is there any way to force gatling to use a later version of async-http-client, which seems to not have the same problem?
thanks
Michael Kohout
